thanks for the links. The box i tried to put on is 60"s in length. I have only 1/2 " on each side to keep the thing up there. Any movement and it falls into the bed even with it tightend as much as I could.
The length of the box must be at least 63" in length to work. I just can't find one that is around 63" - 66". 60 is to short and 70 sticks out from the sides by a couple inches.
This blows cause I really need a box to fit. argghhhhhh!!!!!
